Resize 1081x1081 texture from Terrain.Party to 1009x1009 based on Epic Recommended Landscape Sizes Chart.Exported heightmaps from Terrain.Party are 16bit grayscale and 1081x1081px resolution.You may need to reduce landscape's Scale Z. You now have your landscape from Terrain.Party heightmap. I leave all the settings here to whatever UE4 thinks is best and click Import: Go to Landscape Mode and under Manage click on Import from File. Resizing the heightmap to closest recommended landscape size of 1009x1009 will avoid this problem. However there will be a stetched out effect at the border of your landscape which I explained in-detail in this tutorial and how you could fix it. You could use 1081x1081 without resizing and it will work. This is the closest texture resolution to Epic's Recommended Landscape Sizes. Resize the heightmap texture down to 1009x1009. This is the best and cleanest heightmap texture.

It doesn't affect the heightmap data you will download.Д¬lick on this icon to Export the heightmap.Д®xtract the downloaded zip file. This will show you different visual result of the map. It will return the same heightmap resolution. It doesn't matter how large you sample the area. Important: Every heightmap texture downloaded from Terrain.Party will be 1081x1081px. Use the Plus/Minus icon to sample the region size.

Use the Plus/Minus icons on the left to zoom in/out on the map or use the Mouse Wheel: Some regions in the world will give you better results that others. Don't expect to get good heightmaps from everywhere. Left Click Hold and Drag this square to position it anywhere in the world. This square is your sampled data that will be used to generate the heightmap. Let's generate your very first heightmap in Terrain.Party and bring it into UE4. A very good way to do this is to use a pixel shader to blend between several textures (ex: sand, grass, rock, snow), based on some weights, computed according to the height of each vertex.9 Steps to Your First Heightmap from Terrain.Party Now, for Dimension = 512, cellSize = 8 and maxHeight = 512, the terrain looks like this, which is much better: To use this function, in the vertex shader, replaceДЇloat height = tex2Dlod ( displacementSampler, float4(In.uv.xy, 0, 0 ) ) ДЇloat height = tex2Dlod_bilinear( displacementSampler, float4(In.uv.xy,0,0)) It samples the four pixels nearest to the current coordinates, and interpolates between them, to obtain the average height that the vertex should have. Now, in the LoadGraphicsContent function, call grid.LoadGraphicsContent().Д¬amera camera Grid grid public Game1() We will talk about what happens when changing the Dimension property later. You can try setting the CellSize to any value you want, to see what happens.

The camera will be added to the Components list, and for the grid, we will set the properties CellSize and Dimension to 4 and 256 respectively. Now, add two member to the Game1 class, one for the camera component, and one for the grid, and instantiate them in the constructor of the class. Then go to the game class ( Game1.cs ), and add the VTFTutorial namespace to the using statements. Add to the project the files Camera.cs and Grid.cs.

Let us begin by creating a new project (for Windows or Xbox360). However, this is the simplest and most clear example that shows how Vertex Texture Fetch is used. As this operation is done only once (at loading) and not at every frame ( in the vertex shader), using vertex textures does not have any performance gains for this particular case. Building the terrain mesh from the heightmap texture could be easily done without using vertex textures, by reading the heights at loading time, when building the vertex buffer. Each pixel contains a floating point value, 0.0f being the lowest height, and 1.0f being the highest. When using floating point textures, the principle is the same. The shade of gray that a pixel has determines the height of the terrain at that point, white being the highest, and black being the lowest. A heightmap is a grayscale image, containing the heights of the terrain. We will begin with the simple example of rendering terrain using heightmaps.
